ROLLER SIDE BEARING FOR RAILWAY-CARS.

Specification of Letters Patent.

Application filed October 1, 1909. Serial No` 520,554.

' To all whom may concern:

Be it known that I, JOHN F. OCoNNoR, a

i' citizen of the United States, residing in Chicago, in the county ofCook and State of4 Illinois, have invented a new and useful Improvementin Roller Side Bearings for Railway-Cars, of which the following is aspecitication. n

My invent-ion relates to improvements in roller side bearings forrailway cars.

I-n the accompanying drawing forming a part of this specification,Figure l is a front elevation of truck and body bolsters of a, railwaycar having roller side bearings embodyingmy invention. Fig. 2 is acentral, vertical longitudinal section -of my improved side bearingtaken on the line 2 2 of Fig. 3. Fig. 3 is a plan view. Fig. 4 is avertical section on line4-4 of Fig. 3. Fig. 5 is a detail perspectiveview of one of the roller spacers.

In the drawing-A represents the truck bolster, A1 the body bolster of arailway car.

E is the base or lower bearing plate of my roller side bearing, the samebeing secured to the truck bolster A. It is provided with a reverselyinclined or double cone-faced tread I; to receive the double cone or0ppositely beveled anti-friction rollers C C, the tread 7) heilig curvedabout the king bolt as a center, as will be readily understood from Fig.3 .o't' the drawing. The lower bearing plate B is further provided oneach side of the tread Z) with upwardly projecting flanges or wings 721,provided at the upper portion with overhanging'shoulders or guides b2for interengagement with the corresponding guides (l d1 of the upper ormovable bearing plate D, which contacts with the body bolster A1 or towearing plates A2. secured thereto. The upper or movable bearing plate Dhas 4depending sides (l2,

one of which is furnished with an integral guide (l for engagement vwith.the guide b2 of the lower bearing plate B, and the other of which isprovided with a longitudinal -groove to receive a removable guide d1which engages the corresponding guides b2 of the lower bearing plate B,thus removably securing the upper and lower bearing plates together,while permitting the upper bearing plate to reciprocate in respect tothe lower one. The upper bearing plate D has depending or downwardlycurved end portions (ls which partially overhang or house theanti-friction roller The upper or movable bearing plate D is furnishedwith a reversely inclined or double cone-faced tread d4 for Vtheanti-frictiol'l.`

rollers C C to roll against.

To keep the anti-frictionv rollers C C properly spaced and to cause themand the upper bearing plate to automatically'- return to central ornormal position after each swinging movement of the body and truckholsters about the king bolt in respectrto each other.. when thepressure-or weightV on the side bearing is again relieved, I provide theside bearing with a pair of spacers'F, each having a pair of studs f toventer the hole 'Cl in the anti-friction roller C, one of these spacers Ffitting on each side of the` rollers andl between the ends of therollers and the upwardly projecting flanges or wings b1 of the lowerbearing plate B. The upper bearing plate D also has central guides orshoulders d5 against which the upper portions of the spacers F may en;gage on their inner faces. The spacers F are provided with upwardlyprojecting shoulders or lugs f2 to engage the followers G which fit in acentral chamber or recess D1 with which the upper bearin plate isprovided, and abut against shoul ers d on said bearing plate. A coiledspring H is interposed between the followers G bearing at one endagainst. one follower' and at the opposite end against the other, thespring and the followers being supported in posi tion by a guide stein gwhich is preferably curved about the king bolt as a center, and

lits at its end in suitable slots Z1 in the u per v bearing plate D.As-the Amovement o the upper bearing plate D in either direction istwice that of the axes of the rollers C in the same direction, thespring H is compressed atl each movementso that it tends to restore theparts to their central and nor'- mal position as soon as the pressure orweight is relieved from the side bearing. As the roller treads of thebearing plates are curved about the king bolt as a center, theoppositely beveled or double cone anti-friction rollers C are madecorres ondingly larger at their outer ends thant eir inner ends.
